Jordan said the crime is part of what he described as “a disturbing trend in this city” in which juveniles as young as 13 have been involved in violent crimes.

“I call on parents, the schools and the community to change the cycle,” Jordan said.

Boyer, 34, who had worked as a paramedic for five years, the last two for Santa Clara County Ambulance, was shot while he was driving shortly before noon on April 2 and crashed his car down a ravine in the 5200 block of Keller Avenue. He died two days later.

Boyer, who grew up in Oakland, was in Oakland on April 2 to take his father to a medical appointment. A graduate of Sonoma State University, the Santa Rosa Fire Academy and the Foothill Paramedic Program, Boyer is survived by his wife and family.
